PCF8576C
Fig.19 Synchronization of the cascade for the various PCF8576C drive modes.
Excessive capacitive coupling between SCL or CLK and SYNC may cause erroneous synchronization. If this proves to be a problem, the capacitance of
the SYNC line should be increased (e.g. by an external capacitor between SYNC and VDD). Degradation of the positive edge of the SYNC pulse may be
countered by an external pull-up resistor.
